Simulation envelopes

Spawning Biomass

Simulation envelopes of spawning biomass and catch scaled by unfished biomass. Columns are species, and rows are stock areas. Median biomass is shown by the thick black lines, with the grey region showing the central 95% of the distribution of spawning biomass, and thin black lines showing three randomly selected simulation replicates. Catch is shown as grey bars in the historical period, which represent median catch in the projection, with thin vertical line segments showing the central 95% of the catch distribution.

TAC utilisation

Simulation envelopes of TAC utilisation. Columns are species, rows are stock areas. Heavy black lines show the median TAC utilisation, with thin black lines showing 3 random replicates, and the grey region showing the central 95% of the distribution.

Example replicates

Retrospective biomass

Retrospective assesment model estimates of stock biomass from a randomly selected simulation replicate. Red lines are spawning stock biomass, black lines are total biomass, and grey dashed lines are commercial trawl fishery exploitable biomass. Catch bars show realised catch in grey for the whole simulation period, and in the projection period TACs set by the harvest control rule are shown as hollow black rectangles over the grey catch bars.

Red lines are spawning stock biomass, black lines are total biomass, and grey dashed lines are commercial trawl fishery exploitable biomass. Catch bars show realised catch in grey for the whole simulation period, and in the projection period TACs set by the harvest control rule are shown as hollow black rectangles over the grey catch bars.

Model fits in first year

Assessment model fits to biomass indices in the first year of the projections. Indices are shown as data points scaled by the AM estimates of catchability. Red lines are spawning stock biomass, black lines are total biomass, and grey dashed lines are commercial trawl fishery exploitable biomass. Grey bars show catch in the historical period.

Red lines are spawning stock biomass, black lines are total biomass, and grey dashed lines are commercial trawl fishery exploitable biomass. Grey bars show catch in the historical period.

Standardised residuals of assessment model fits to biomass indices. Point colours correspond to fleets, while point shapes are stock areas.
